Sigma Chess 6 Endgame Databases
September 9, 2002
_____________________________________________________________________
The endgame database generators will generate the following databases:
Ñ KQKR (includes KQK)
Ñ KBNK
Sigma Chess Pro additionally supports the following databases:
Ñ KQKB
Ñ KQKN
Ñ KRKB
Ñ KRKN (includes KRK)
Ñ KBBK
Note that the KPK database is built in to Sigma Chess (because it's much smaller), and that
there thus is no database generator for this ending. Note also, that the KQK and KRK
databases are included in the KQKR and KRKN databases respectively.
Each database takes up about 3.7 Mb disk space. The generation process takes a few
minutes per database.
You don't have to generate these databases for Sigma Chess to run. If the program ends up
in one of the above endgames, it will try to consult the corresponding database. If there
is no database (or Sigma Chess can't find it), the program simply starts thinking using
it's normal search engine.
NOTE: Sigma Chess expects the endgame databases to reside in the "Endgame Databases"
folder. If this is not the case, Sigma Chess can't find them.
Have fun!!
